IMAGE FORMING APPARATUS THAT CARRIES OUT COLOR REGISTRATION ADJUSTMENT, CONTROL METHOD THEREFOR, AND STORAGE MEDIUM |
摘要 |
An image forming apparatus which is capable of improving the accuracy of detecting the amount of misregistration. A control unit controls a plurality of image forming units so as to form a color registration pattern on a image bearing member. A detection unit detects diffusely reflected light reflected on the image bearing member and the color registration pattern. The control unit compares a first output value output by the detection unit detecting the surface of the image bearing member with a second output value output by the detection unit detecting a low-reflectivity toner pattern formed on the image bearing member, and determines a density of the color registration pattern corresponding to the low-reflectivity toner pattern based on a result of the comparison.
